With reference to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the structural representation that the embodiment of the present invention turns to lining, Fig. 2 is the structural representation that the embodiment of the present invention turns to lining to coordinate with rotating shaft 5, and Fig. 3 is the end view that in Fig. 2, the embodiment of the present invention turns to lining and rotating shaft 5 fit structures.The lining that turns to that the embodiment of the present invention provides comprises inner tube 1, and inner tube 1 lateral wall is arranged with rubber layer 2, and the lateral wall of rubber layer 2 is arranged with outer tube 3, and inner tube 1 coaxially arranges with outer tube 3, rubber layer 2 by inner tube 1 together with outer tube 3 secure bond; Minimum in the direction of the rubber distribution height of the both sides end face of rubber layer 2 is the highest in the direction of the first diameter 8 that turns to bush end face described in edge, turning to bush end face Second bobbin diameter 9 described in edge, and reduce continuously to Second bobbin diameter 9 directions from the first diameter 8 directions.
The lining that turns to that the embodiment of the present invention provides consists of jointly inner tube 1, outer tube 3 and intermediate rubber layer 2.Particularly, the method that can adopt the vulcanization of rubber is closely fixed together inner tube 1 and outer tube 3 and rubber layer 2, and to form an interlayer be rubber turns to lining.Because rubber exists certain elasticity, so, described in to turn to lining be flexible liner, thereby can provide buffering for the interaction force of two attaching partss being mated.And described rubber has quite high intensity in its elastic limit, so, described in turn to lining can meet again vehicle demand to its rigidity under normal motoring condition.In addition, rubber layer 2 has specific filling shape, intermediate host is partly complete filling, and the rubber distribution height of the both sides end face of rubber layer 2 has continually varying characteristic from high to low, described in can making, turn to lining to there is the characteristic that flexibility size that the difference along with the anglec of rotation has also changes thereupon.Due to, minimum in the direction of the rubber distribution height of the both sides end face of rubber layer 2 is the highest in the direction of the first diameter 8 that turns to bush end face described in edge, turning to bush end face Second bobbin diameter 9 described in edge, and reduce continuously to Second bobbin diameter 9 directions from the first diameter 8 directions, so, the described lining rigidity in the direction of the first diameter 8 that turns to is the highest, in the direction of Second bobbin diameter 9, rigidity is minimum, from the first diameter 8 directions to Second bobbin diameter 9 directions, the described rigidity of lining that turns to little by little reduces continuously, on the contrary, described in, turn to the flexibility of lining relatively to strengthen.
Particularly, with reference to Fig. 4 and Fig. 5, Fig. 4 is the rubber scatter chart that the embodiment of the present invention turns to the rubber layer both sides end face of lining, and Fig. 5 is the change curve that the embodiment of the present invention turns to lining axial stiffness.In Fig. 4 f1 be the rubber distribution height of both sides end face of rubber layer 2 with the change curve of angle, in Fig. 5, N1 turns to lining axial stiffness with the change curve of angle described in being.In figure, abscissa represents angle, angle be zero position with described in turn to bushing rubber layer 2 both sides end face corresponding along the height of the first diameter 8 directions.Through overtesting, the corresponding f1 of known different automobile types and N1 curve are different, and curvature changes different.Three kinds of different distribution curves in figure, have been exemplified.Rubber layer 2 has specific filling shape, intermediate host is partly complete filling, on lining axial direction, not contour sizing material is filled at the position that is positioned at two ends, and along in the direction of the first diameter 8, rubber has along the axial maximum distribution height of lining, and on the hand of rotation of forward and inverse hour hands, have specific height and distribute, highly distribute and present the functional relation of f1 curve with corner, lining two ends height is distributed as and is arranged symmetrically with.Along with the increase of corner, slope of a curve is negative value, and slope presents the trend diminishing, mean near larger corner, the speed highly declining, described in turn to the speed of lining Stiffness faster.The described initial installation site of lining that turns to, for having rubber distribution extreme higher position, along with the increase of angle, reduces highly gradually, and rigidity weakens gradually.
With reference to Fig. 8, Fig. 8 is that the embodiment of the present invention turns to lining to be installed on the structural representation on rear overhang rack.During use, described turning to after wearing rotating shaft 5 in lining, be installed between the swing arm 4 and steering swivel 6 of rear overhang rack, described rear suspension is between vehicle body and wheel.The described outer tube 3 of lining and one end of swing arm 4 of turning to fixed, rotating shaft 5 is connected with steering swivel 6.The initial installing condition that turns to lining is at vehicle during in semi-load, swing arm 4 and the installation site that turns to the installation position of lining a little less than the interior survey of swing arm 4 and vehicle body, now install while turning to lining, require to turn to rubber layer 2 in lining to there is the direction of most significant end face height consistent with the direction of tilt of swing arm 4 main bodys, vertical with the table plane of rotating shaft 5 two ends flats structures.When automobile normal running, described, turn to being subject on force direction of lining, the rubber distribution height of the both sides end face of the described rubber layer 2 that turns to lining is the highest, be that the middle rubber filling of inner tube 1 and outer tube 3 is maximum, thereby described in turn to lining to there is higher rigidity, the relative stability in the time of can guaranteeing described automobile normal running between vehicle body and wheel; When automobile turning, the described lining that turns to can turn an angle according to the turn radius of current automobile and turning speed, and then described in making, turn to lining to there is the flexibility corresponding with current automobile turning state, described flexibility can allow the wheel being connected with steering swivel 6 to produce certain deflection angle that is conducive to motor turning, thereby can realize the function of automobile back wheel follow-up steering.
Particularly, turn radius during automobile turning has determined the angle of inclination that described auto body is relative with turning speed, the inclination of vehicle body causes the variation at swing arm 4 angles of inclination, due to swing arm 4 with described in turn to lining to be fixedly connected with, so, described in turn to lining along with certain angle is rotated in swing arm 4.Because the increase of the described flexibility that turns to lining along with its rotational angle increases, so, described in turn to lining to show the flexibility of answering in contrast according to the different turn radius of vehicle and turning speed.Automobile back wheel by steering swivel 6 with described in turn to lining to be connected, and the size at follow-up steering angle turns to the size of lining flexibility described in depending on, turns to the flexibility of lining larger, described follow-up steering angle is larger.Because the described rotational angle that turns to lining depends on turn radius and the turning speed of described automobile, so, the trailing wheel of described automobile can produce a follow-up steering angle to a certain degree that is of value to motor turning automatically according to the size of its turn radius and turning speed, although this follow-up steering angle is very little, can improve to a certain extent the manoevreability of automobile.In galloping, vital effect can be played in this follow-up steering angle, can make vehicle can alleviate according to current turn radius and the speed of a motor vehicle oversteer or the understeering of vehicle when turning.Thereby reach the function of automobile back wheel follow-up steering.

With reference to Fig. 4, further, the rubber distribution height of rubber layer 2 both sides end faces can be according to y=a x with the variation relation of described angle
2or y=a x
1/2function curve, wherein x represents the diameter at the rubber layer arbitrary rubber distributed points of 2 both sides end face place and the angle of described the first diameter, y represents the rubber distribution height of described arbitrary rubber distributed points, a is predefined coefficient, and 0.5≤a≤5.The rubber distribution height of the larger expression rubber layer 2 both sides end faces of value of a declines sooner with the increase of described angle.In addition, the value of different vehicle a is different.As functional expression y=a x
1/2, value one timing at a, is compared to y=a x
2functional relation, the rubber regularity of distribution of the corresponding 2 rubber layer both sides end faces of this functional relation is more conducive to the quick response of vehicle follow-up steering, is more conducive to turn, therefore preferred y=ax
1/2function curve.The present embodiment has only been listed some simple more common functional relations, and concrete functional relation can design and select according to concrete vehicle and particular case.
